We present a 7T coil system which allows the head to be rotated by greater than 90 degrees to investigate the effect of orientation upon the T2* contrast and B0 distribution in the brain. A patch antenna is used to create traveling wave excitation. The subject is placed in the sphinx position with face towards the patch antenna. A six-element U-shaped receive coil was built to wrap over the crown of the head providing high enough SNR for high resolution T2* imaging. Imaging in regular supine position was also done for comparison.
